bing11,
I don't have a clue what you're talking about?
Did you already have this hack installed and it worked and now it doesn't?
Is this the first time you've tried to install this hack?
Did you follow Jason's installation instructions. They are pretty straight-forward, easy to understand and follow?
Is this problem you're having because you tried to add thumbnails to Tag Searches (see 02 JUN 2008 Post # 169)?
Did you add the forum numbers to the Thread Thumbnail plugin array (see 02 APR 2008 Post # 114)?
If you are using the Thread Thumbnail Search plugin did you tweak Search.php (see 02 APR 2008 Post # 112)?
Is Thumbnail Creation turned ON?
AdminCP > vBulletin Options > Message Attachment Options > Thumbnail Creation
I have mine set to 'Yes, with border and dimensions' (which just may be the default, I don't know).
Also, in Attachment Manager gif, jpg, jpeg Thumb column all read Yes (Yes?).

If you need help you need to ask better questions, detail what your problem is, be a bit more specific. Okay?
